This invention relates particularly to a fastening latch for swinging windows of the easement or awning type.

An object of the invention is to provide a L fastener having a latch that is adapted to J hold the window in engagement with the window frame and which is provided with a handle member for raising and lowering the latch member and for swinging the sash into A and from the opened and closed positions.

l Other objects of the invention are to provide a combined sash lock and handle that will be superior in point of simplicity, inexpensiveness of construction, positiveness of A operation, and facility and convenience in use and general eiiciency.

In this specification and the annexed drawings, the invention is illustrated in the form considered to be the best, but it is to be understood that the invention is not limited to such form, because it may be embodied in other forms, and it is also to be understood that in and by the claims following the description, it is desired to cover the invention in whatsoever form it may be embodied.

In the accompanying one sheet of drawings Fig. 1 represents a side elevation of'a sash fastener, constructed in accordance with my invention, and partly broken away, to show 3o the interior thereof. Y

Fig. 2 is an end view of Fig. 1.

Fig. 3 is a side view-of a modified form of fastener.

Fig. 4 is an end view of Fig. 3.

Fig. 5 is a side elevation of a still further modified form of fastener.

Fig. 6 is an end view of Fig. 5..

Fig. 7 is a perspective view of a still further modification of a sash fastener constructed in accordance with my invention.

In detail, the construction illustrated in the drawings comprises a portion of a window frame indicated by the numeral 1 and having a sash 2 of the awning or easement type that is adapted to be moved into and from engagement with the window frame. The fastener for holding the window sash in engagement with the window frame is and may be of any of the forms shown in the various figures on the drawings. The form of device shown in Fig. 1 consists of a plate 3 secured to the window sash and has arm members 4 extending outwardly therefrom. A latch bolt 5 is slidably guided to movement in a vertical direction in the plate 3 between the arms 4 55 and the latch 5 is adapted to engage an opening through the strike plate 6 on the window frame 1. A handle member 7 is pivoted intermediate its ends at 8, to the end of the arm 4 and the opposite end 9 of the handle 7 mov- 60 ably engages the latch 5 to raise or lower the same. In order to open the sash 2, the handle 7 is depressed on the outer end to raise the latch 5, which action permits the sash to be swung open. lVhen the sash moves from the opened into a closed position, by movement actuated by pulling on the handle 7, the latch 5 will automatically ride up on the strike plate 6 and enter the slot therein to hold the sash in the closed 7o position in the window frame.

In the modified form of device shown in Figs. 3 and 4, I provide a bracket plate 10, that is adapted to be mounted on the window sash, and which has an arm 11 extending out- 75 wardly therefrom. A handle member 112 is pivoted at 13, intermediate its ends, to the end of the arm 11 whereby the free end 14 of said handle member may drop belowthe plane of the arm 11 and function as a latch member 80 to engage the window frame.

In Figs. 5 and 6 the form of construction is similar tothat shown in Figs. 3 and 4 with the exception that the arm member 15 is secured directly to the window sash and the handle member 16 is pivoted thereon at 17 so as to allow the'free lower end 18 thereof to drop below the plane of the arm 15 and engage the strike plate on the window frame to hold the sash in the closed position.

InFig. 7, an arm member 19 is secured to the sash 2O and the outer end of the arm 19 is provided with a-handle 21 thereon for mov- `ing` the sash relative to the window frame 2.

A handle member 23 is pivoted at 24 within 95 the arm 19 and the free, lower end 25 of the handle member 23 is adapted to drop down and engage the strike plate 26. In the form of device shown in Fig. 7 I have provided a separate handle 2l on the arm for opening or 100 lll Y closing the sash and a handle 23 0n the latch member for engaging or ,disengaging the same with the window frame independently of the arm member.

I-Iaving thus described this invention, what I claim and desire to secure by Letters Patent l. A easement fastener comprising a base projecting beyond the plane of the face of a swinging Casement mounted in a easement frame; and a latch disposed in line with the projection of the base and pivoted between its ends to said base, the lower end of the latch being heavier thanthe upper end thereof, whereby the heavier end of the latch will drop by gravity behind the Casement frame when the easement is closed, the upper end of the latch having a handle thereon to effect pivotal movement of the latch to disengage it from the easement frame. 42. A Casement fastener comprising a base projecting beyond the plane of theface of a swinging easement mounted in a easement frame; and a latch disposed in line with lthe projection of the basey and pivoted between its ends to said base, the lower end of the latch being heavier than the upper end thereof,-

whereby the heavier end of the latch will drop by gravity behind the easement frame when the yeasement is closed, said latch being curved along its length, on an arc corresponding to the arc of movement prescribed by the swing- 1 ing side of the easement whereby the heavier end of the latch will ride over the Casement Y frame into the latching position as the casement is swung into the closed positiomthe upper end of the latch having a handle thereon to effect pivotal movement of the latch to f disengage it from ther Casement frame.

3. A latch for a swinging window comprising a base secured to one side of the window sash having agrooved arm extendedtherefrom and terminating in a handle grip; a latch member disposed lengthwise of the grooved c portion Vof the arm and pivoted thereto midway between itsvopposite ends; the lower end of the latch being heavier than the upper end thereof, whereby the heavier lower endiof the latch will drop by gravity behind a plate on window frame when the sash is closed ;l and means mounted on the arm related to the upper end of the latch to force the upper end of the' latch downwardly and to raise the lower end of the latch.

In testimony whereof, I have hereunto set my hand at San Francisco, California, this lith day of January, 1929.
